Installation
Bolt the assembly to the floor using the four mounting brackets
located on each corner of the system (A). The mounting pattern
is a 7.5” x 16.3” rectangle. Mounting screws can be up to 7/16
of an inch in diameter.
Connect the drive air supply to the 3/4 inch FNPT 5 micron
inlet filter (B). The air supply piping should be 3/4 inch pipe
diameter or larger.
Connect the discharge line to the 1 inch FNPT pipe port located
on the back of the system (C). The discharge piping should be
3/4 inch pipe diameter or larger.
WARNING: Make sure that the discharge piping
components are rated for 230 psi. If the discharge piping
has a lower pressure rating it should be protected by a
safety relief valve.
Startup
This booster can be operated with one or both boosters. To
operate with both boosters, open the inlet valves (1) and
discharge valves (2). To operate with one booster, close the
inlet valve and discharge valve of the desired booster.
There is a discharge pressure regulator for each of booster. Pull
up on the black knob on the top of the booster to unlock it. Turn
the knob to increase or decrease the desired discharge pressure.
The regulators are self-relieving. If one is set for a higher
pressure, the other regulator will try to vent the pressure. When
both boosters are operating at the same time, the regulators
must be set to the same pressure. The location of the
pressure gauges (3) and the discharge pressure gauges (4) are
shown above. When the boosters have pressurized the
downstream components to the maximum desired pressure,
they will stall. If one of the self-relieving regulators vents at
the stall condition, turn the knob clockwise until the venting
stops. The maximum recommended discharge pressure is 230
psi. If the supply pressure is higher than 115 psi, it is possible
to set the regulators so the system exceeds the maximum
discharge pressure of 230 psi. During startup, do not turn the
regulators to their highest setting, but slowly increase the
regulator settings until the desired pressure is reached.
WARNING: Do not exceed the maximum allowable
discharge pressure of 230 psi.
Operation
The system is fully automatic. When the desired discharge
pressure has been reached, and no flow is required, the
boosters will stop automatically. They will restart when the
discharge pressure drops about 5 psi.
Maintenance
The air supply filter should be checked periodically. If a
booster needs to be removed for service, close the air supply
valve and the discharge valve. The discharge valve will vent
the pressure between the two valves and the booster pressure
gauges should both read zero. The idle booster can be safely
removed and repaired while the other booster continues to
operate.
